Thermostat check

Check without thermostat removal


    Before removing and checking operability of the thermostat, make sure that problems with cooling of the engine arose not owing to falling of level of the heat-carrier, or weakening of a belt of a drive of GRM. Check serviceability of functioning of the indicator on a combination of devices. If the engine insufficiently quickly gets warm to working temperature (according to indicator indications), it is necessary to remove the thermostat (see. The section Removal and thermostat installation) and to check, whether it is jammed in open situation, - in case of need make replacement. The option is not excluded also that the thermostat simply was not established during performance of the last service of the car. Car operation at the removed thermostat is characterized by the increased fuel consumption and excessive concentration of toxic components in the fulfilled gases. At an overheat of the engine feel the top hose of a radiator, - if the hose is not heated-up, therefore the thermostat is jammed in a closed position and the heat-carrier continues to circulate on a small circle, without getting to a radiator. Replace the thermostat. Otherwise it is necessary to consider the other possible causes of an overheat of the engine (see. The section Diagnostics of malfunctions in Head Introduction at the beginning of the Management).

Check with thermostat removal


    Remove the thermostat (see. Section Removal and thermostat installation).
    Lower the thermostat on a piece of a twine in the capacity filled with water, - the thermostat should not concern capacity walls.
    Lower in water the thermometer and start to heat up capacity, watching behavior of the main and additional valves of the thermostat. Compare results of measurement to requirements of Specifications of the Head of System of cooling, heating, ventilation and air conditioning.
    Take the thermostat and let's to it cool down, - valves should be closed completely. The faulty thermostat is subject to replacement.
